The IMO UB10D3030A is a robust UL489 miniature circuit breaker (MCB) designed to provide dependable protection against overloads and short circuits in industrial and commercial electrical installations. Manufactured by IMO Precision Controls, this compact protective device is suitable for machinery, automation systems, control panels and electrical distribution equipment.
Featuring a 3-pole configuration, a 30 A rated current and a D curve tripping characteristic, the UB10D3030A is particularly suitable for three-phase circuits supplying motors, transformers and other inductive loads. Its D curve response accommodates the temporary high inrush currents commonly produced when industrial equipment starts.
With a 10 kA short circuit breaking capacity, thermal-magnetic protection and a compact DIN rail mounting format, the UB10D3030A delivers effective fault interruption in demanding environments. It provides machine builders, panel manufacturers and electrical engineers with a reliable solution for branch circuit protection.
Miniature circuit breakers automatically disconnect an electrical circuit when excessive current is detected. The thermal element responds to sustained overload conditions, while the magnetic element provides rapid operation during severe short circuit faults. This helps protect cables, machinery and connected equipment from electrical damage.
The D curve characteristic of the IMO UB10D3030A permits higher temporary inrush currents before magnetic tripping occurs. This makes the breaker suitable for industrial equipment that draws substantial current during start-up while maintaining dependable protection against genuine electrical faults.
